The shells of Oxychilus koutaisanus mingrelicus unknown earlier for Ukraine were discovered among the materials collected on the territory of the Donetsk Region in 1990-th. The unpdated information about the distribution on the territory of Ukraine of another Caucasian species, Stenomphalia ravergiensis , is provided. The presence of these species in the south-east of Ukraine can be result of the anthropochory.

The structure of reproductive tract of 15 species and subspecies (forms) of European (mainly Alpine) and South African Orculidae has been studied. For 12 of them the spermatophores were discovered and described or the characters undoubtedly indicating presence of spermatophore have been found (inner structure of the epiphallus). The presence of spermatophores as such is established for 5 species. Hypotheses about the possible historical relationships among subfamilies and genera of Orculidae and among species in the genus Orcula are presented.

The present-day data on geographical distribution and variability of three recent species of Aenigmomphiscola Kruglov et Starobogatov, 1981 (Lymnaeidae) are reviewed. More specific information concerning type series of two Aenigmomphiscola species is obtained. It is revealed that the species Ae. uvalievae and Ae. kazakhstanica cannot be distinguished in syntopy by their conchological traits, and, possible, these are conspecific. Judging from reliable records, the range of the genus Aenigmomphiscola covers a part of the East-European (Russian) plain, Southern Urals, the southern part of Western Siberia (including Altay), and Central Kazakhstan. Perhaps, representatives of the genus will be found in the future in another parts of Siberia and adjacent territories.

Limpet fauna of the Holarctic genus Acroloxus Beck, 1837 was examined in Lake Baikal. Morphology of protoconch and teleoconch of three species (A. baicalensis Kozhov, 1936, A. orientalis Kruglov et Starobogatov, 1991 and possible new Acroloxus species) was studied with SEM. Additional shell characters were described for A. baicalensis, collected from its type locality. Distribution of representatives of the genus Acroloxus in Lake Baikal and its basin was discussed.

The analysis of L. maximus allozymic variability on the Dnieper right-bank Ukraine territory testifies to the balanced proportion of homo- and heterozygotic genotypes in populations in most cases. Thus, this species is reproduced mostly amphimicticly. In some cases, probably, automixis takes place and leads to genotypes fixing in homozygotic state. This specis is characterized with stable chromosome numbers (n=31, 2n=62) and chromosome arms (NF=124). L. maximus morphometric parameters vary greatly but geographic tendencies this species morphological variability have not been found.

Shells of one of Physa Draparnaud, 1801 species, inhabiting the rivers and reservoirs of the North Azov Sea coast clearly fit the re-description and figures of North American Physa skinneri Taylor, 1954. The illustrated description of the species from Ukrainian populations is provided here; some data on its distribution in Ukraine and in entire Eurasia are discussed. It is quite possible that these Eurasian conchological «twin» for Ph. skinneri should be attributed to one of the Old World aborigine species. To solve this problem the type materials for most common European Physa species, as well as their variability, anatomy and other characteristics should be studied.

Among a small collection of Polyplacophora from the Hans-Georg Müller collection at the Bavarian State collection we recognized an undescribed species of Leptochiton Gray, 1847, which is described herein. The species is minute (2.1 mm) and shows a strong sculpturing of roundish granules, quincuncially arranged on the tegmentum. The species’ small size, long intersegmental spicules, and the high tail valve with a concave postmucronal slope, easily separates this species from its congeners. In addition, based on the new material, we are able to raise the number of chiton species identified in Sri Lanka to 24, although three of them require further study. The former known species are compiled to make an easy tracing of the Sri Lanka chiton fauna possible. Within this evaluation we transferred the species Tonicia pectinoides Sykes, 1903 and Tonicia ceylonica Leloup, 1936 to the genus Lucilina, following the concept of Schwabe et al., [2008]. Besides the new species, Rhyssoplax maldivensis (E. A. Smith in Gardiner, 1903) and Acanthochitona leopoldi (Leloup, 1933), were the first time mentioned from Sri Lanka. Comparisons with the chiton faunas of the Andaman Sea area and the Maldives show that minimal species overlapping occurs, despite a similar species numbers in the three areas discussed.

Minute turriform conoideans comprise a considerable fraction of the taxonomically undescribed diversity of marine mollusks. Species of the genus Lienardia, Jousseaume, 1884, extremely diverse in shallow water tropical marine communities, have long been overlooked by taxonomists and a high proportion of them remain undescribed to date. Development of a specialized collection technique, based on deployment of lumun-lumun nets have provided a vast amount of material on this group and enable several new species to be distinguished. Examination of material from the Philippines and other regions of tropical Indo-Pacific revealed five new species of the genus Lienardia, which are being described as L. acrolineata, L. grandiradula, L. multicolor, L. roseangulata and L. tagaroae. Examination of radulae in described species of the genus Lienardia shown unexpected morphologic diversity. It suggests that either rapid morphological specialization of Lienardia members had taken place in the evolution of the genus, or similarity of shells in Lienardia species is possibly convergent.

During the study of the conchological variability of the land molluscs of the genus Chondrula in the south-east part of Ukraine and Crimea was discovered the form with specific structure of the aperture teeth which does not correspond to description of the known conchological forms of the widespread species Ch. tridens. The shells of Ch. tridens martynovi subsp. nov. with well developed aperture teeth are characterized by the following characters: 1) the angular tooth is not limited to the knoll or short comb on the aperture edge but sharply bends down and forms a low fold parallel to the parietal lamella; 2) palatal and suprapalatal teeth fuse to form the single well visible crestform lamella. Shells with incompletely formed teeth can resemble Ch. tridens tridens. The preliminary map of the distribution of Ch. tridens martynovi and Ch. tridens tridens on the territory of Ukraine was compiled on the basis of the materials of the State Museum of Natural History (Lviv). Brephulopsis konovalovae sp. nov. differs from B. bidens in shorter shells, more convex whorls and ribbed surface. The populations of B. konovalovae and B. bidens live sympatrically in the locus typicus in the mountain Crimea and do not form transitional forms.

During the investigation of the land mollusc fauna of the Donetsk upland (Eastern Ukraine) and adjoining territories three new species of the genus Helicopsis were discovered. One of them, H. subfilimargo sp. nov., is similar conchologically to Crimean H. filimargo, but clearly differs from it in a number of anatomical characters. The photographs illustrate the intrapopulation variability of the conchological and some anatomical features of H. subfilimargo sp. nov., H. martynovi sp. nov., H. luganica sp. nov. The conchological variability and some peculiarities of the internal structure of H. dejecta from Donetsk upland and adjoining territories are also demonstrated.

Population genetic structure of the land snails of the genus Brephulopsis (B. cylindrica and B. bidens) and their hybrids has been studied using of three polymorphic loci of esterases of foot tissues. Genetic patterns of allozyme variability of hybrid forms were similar to those for B. bidens. A similar result is obtained when using multilocus genotypes allozymes. On the other hand, the hybrid forms are characterized by an intermediate (“chimerical”) shell morphology between the two parental species. The values of effective population size were estimated by the Slatkin method of “private” alleles and the Kohn’s rarefaction curve method. These values were in the range from 20 to 60 individuals.

The history of study of Siberian freshwater malacofauna between the end of XVIII and the middle of XX centuries (year 1952) is outlined. Data about professional malacologists, who studied Siberian molluscs, are given as well as information about most important collections of Siberian freshwater malacofauna of this period. The history of formation of continental molluscs collection of the Zoological Institute RAS (formerly Imperial Zoological Museum in SanktPetersburg) is traced. The history of study of Siberian freshwater molluscs is divided into three stages: “primordial” (second half of XVIII — middle of XIX centuries), “expeditionary” (middle of XIX — middle of XX centuries), and “regional” (middle of XX century — present).

A brief review of distirbuiton of populations of Rapana venosa in the World Ocean is presented. Short information concerning the formation of metapopulation of R. venosa in the Black Sea and taxonomical history of the species are given. The ecomorphs found off Crimean shores were examined with the emphasis to ecological conditions. It has been demonstrated that presently Rapana metapopulation in the Black Sea consists of numerous populations which differ primarily in conchological characters and size structure. Trophic specialization entails appearance of dwarf forms and influences formation of shell coloration. Studies of protoconchs allowed to conclude that colour pattern is determined on the earliest stages of shell development and later is influenced by environmental factors during the shell growth. The shell characters were compared in several Rapana populations and intrapopulation variability, age and sexual differences were demonstrated. Starting in 2007 the relative shell growth has been increasing despite the normal tendency of slowing of the growth rate with age. This phenomenon is connected with improvement of ecological situation in general, and, the most important, with increasing of forage reserve of Rapana. The pathways of infraspecies forms formation are presented in relation to possible scenarios of environmental changes.

The shell and radula comparative and illustrated description of all three genera of the family Valvatidae (Valvata s.str., Cincinna and Borysthenia), inhabiting the European fresh-waters are provided. Special emphasis paid to the embryonic shell and radula morphology of Cincinna piscinalis (Müller, 1774) — one of the most common valvatid species in Ukraine. Details of the protoconch of Borysthenia menkeana (Jelski, 1863) is studied with aid of the scanning electron microscopy for the first time. Embryonic shell of those species belonging to all genera discussed possesses identical type of ornamentation («woolen stocking »); it is revealed that valvatid species can be distinguished by proportions of their protoconch and partly by its size. Differences in dimensional characteristics of a protoconch confirm and complete the concept of generic independence of the discussed valvatid groups. Radula of valvatid is highly variable intraspecifically; its aptitude for the species differentiation is limited and requires of additional detailed study of significant set of new data.
